bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7 FVREN: Fixed Voltage Reference Enable bit
1 = FVR circuit powered on
0 = FVR circuit not enabled by FVREN. Other peripherals may enable FVR.
bit 6 FVRST: Fixed Voltage Stable Status bit
1 = FVR is stable and can be used.
0 = FVR is not stable and should not be used.
bit 5-0 Unimplemented: Read as ‘0’.
